Presently, a typical technology of plate bending by flame and water is adopted for ship-hull curved plate forming in shipbuilding industry, which is called line heating abroad. It is very difficult to realize controlling the flame accurately. The line heating technology depends on experienced workers by manual work in shipyards. Laser bending is a new and flexible sheet metal forming technology, which utilizes the non-uniform thermal stress induced by laser irradiation to form sheet metal. Because the...
